Yes, I think Bitcoin is more useful than gold, for example :
in transactions Bitcoin more simple than gold, Using Bitcoin all people can make a transactions only 1-5 minute.
Bitcoin simple, secure and fast than gold
In my opinion if investment in gold is good for those who already have a lot of money, but will be smarter if their funds are put on bitcoin, because bitcoin can be faster in the shipping process, and the price is really attractive from the lower classes to the rich
